Portable terminal

Abstract

A portable terminal includes a touch pad that displays an icon and detects a touch. A camera images a direction in which light of a display of the touch pad travels. A point of view is detected to which an eye of a face imaged by the camera is turned. A position of the point of view is detected and a cursor is displayed on the touch pad according to the position of the point of view on the touch pad output from an information management unit. An input condition management unit determines whether or not a preset input condition is satisfied for an input by a touch to a preset special region of the touch pad and an input of the position of the point of view on the touch pad, and an application program is activated corresponding to the icon according to the determination that is made.

1 . A portable terminal, comprising:

         2 . The portable terminal according to  claim 1 , wherein the icon is not displayed in the preset special region of the touch pad. 
     
     
         3 . The portable terminal according to  claim 2 , wherein the point of view is not detected in the preset special region of the touch pad. 
     
     
         4 . The portable terminal according to  claim 3 , wherein the preset special region of the touch pad is selected from a plurality of regions that come in contact with an edge of the touch pad and set. 
     
     
         5 . A portable terminal, comprising:
 a touch pad that displays an icon and detects a touch;   a camera that images the periphery of the touch pad;   a detecting unit that detects a finger type including a first finger and a second finger of a hand imaged by the camera;   an information management unit that outputs the finger type detected by the detecting unit and a touch position of the touch pad;   a cursor display unit that performs control such that a cursor is displayed on the touch pad according to the touch position of the touch pad by the first finger output from the information management unit;   a condition management unit that determines whether or not a preset input condition is satisfied for an input of the touch position of the touch pad by the first finger and an input of the touch position of the touch pad by the second finger which are output from the information management unit; and   an application program executing unit that activates an application program corresponding to the icon according to the determination of the condition management unit.   
     
     
         6 . The portable terminal according to  claim 5 , wherein the camera is installed in the portable terminal so that an imaging optical axis of the camera is tilted in a direction of the touch pad in order to image the periphery of the touch pad. 
     
     
         7 . The portable terminal according to  claim 6 , wherein the detecting unit detects a finger type including a first finger, a second finger, and a third finger of the hand imaged by the camera,
 the condition management unit determines whether or not a preset input condition is satisfied for an input of a touch position of the touch pad by the first finger and an input of a touch position of the touch pad by the second finger or the third finger which are output from the information management unit; and   the application program executing unit activates an application program corresponding to the icon or displays a menu of an application program corresponding to the icon according to the determination of the condition management unit.   
     
     
         8 . A portable terminal, comprising:
 a touch pad that displays an icon and detects a touch;   a camera that images a direction in which light of a display of the touch pad travels;   a detecting unit that detects a point of view to which an eye of a face imaged by the camera is turned;   an information management unit that outputs a position of the point of view detected by the detecting unit on the touch pad;   a cursor display unit that performs control such that a cursor is displayed on the touch pad according to the position of the point of view on the touch pad output from the information management unit;   a switch input unit;   an input condition management unit that determines whether or not a preset input condition is satisfied for an input by the switch input unit and an input of a position of the point of view on the touch pad output from the information management unit; and   an application program executing unit that activates an application program corresponding to the icon according to the determination of the input condition management unit.   
     
     
         9 . The portable terminal according to  claim 8 , further comprising:
 a microphone unit; and   a voice recognizing unit that recognizes a voice signal input by the microphone unit,   wherein the input condition management unit determines whether or not the preset input condition is satisfied for an input of a recognition result by the voice recognizing unit, the input by the switch input unit, and the input of the position of the point of view on the touch pad output from the information management unit; and   the application program executing unit gives an instruction to an application program which corresponding to the icon and is being executed according to the determination of the input condition management unit.   
     
     
         10 . The portable terminal according to  claim 9 , wherein two cameras are disposed as the camera, and
 the portable terminal further comprises an image recognizing unit that recognizes a face from each of two images captured by the two cameras, calculates a distance to the recognized face from a difference between the two images, and extracts an eye of the recognized face.
